We have an ally in Easter Euorpe... Georgia. Georgia has a breakaway Provence called South Ossetia. South Ossentia is an ally of Russia. Georgian President Mikhail Saakashvili has said time and time again that he would take back South Ossentia. Russian "Prime Minister" Vladimir Putin said that if Georgia tries they will be sorry.
Apparently Georgia has tried. Russia has responded with air strikes and sending in tanks.
Not good. If this escalates you could see Russia invading Georgia and the U.S. obligated to help its ally.
Keep a close eye on this one. It could get ugly.
